The khadakhad daant is the result of dark magic, created when cobras are injected with a mixture of their own venom and other ingredients closely guarded by the Dark Brotherhood. Magi will notice that their cobra begins to eat teeth, taken from anywhere they can get them but with a marked preference for the baby teeth that children lose. They will then begin to grow enough to shed their skin but this time they also shed everything underneath it, until they're nothing but bone. The teeth they've eaten become part of them in the form of their rattle, which some say they shake when death is approaching, especially when it comes for a child. The khadakhad daant is an antisocial creature and should be handled with great care, even if their magi previously had a close relationship with them.
